SenseTemp is:

• Small: The resistive temperature detector (RTD) elements are 2 mm x 4 mm x 1 mm, making them thermally responsive and great for measuring small or dynamic point heat sources. The interface PCB is also small and easy to mount to a mobile system or within existing equipment.
• Battery Powered: including Li-Poly & USB power banks
• Wireless Option: to make test setup faster and more flexible
• Accurate: to ensure that temperature data is useful, actionable, and repeatable
• Sensing
  • Sensor: platinum resistive temperature detector (RTD) driven by MAX31865
  • Channels: 4
  • Accuracy: ±0.32°C @ 0°C and ±0.39°C @ 100°C (see below)
  • Range: -50°C to 260°C (when using silicone harness)
• Actuation (SenseTemp TEC only)
  • Thermo-electric cooler (TEC) driver: VNH5019A + necessary passives for 12 V Peltier junction (@ 5 A or less)
  • Auxiliary switchable power output (12 V @ 1 A) for driving fan or other device
• Sensor Cable Harness
  • Connector: single 16-pin IDC header breaks out to 4 x four-wire RTD leads
  • Ribbon cable: 30 AWG, 0.025" pitch, silicone insulation
  • Available cable lengths: 0.4 m, 0.7 m, 1.5 m
